Lesegert To all whom t may concer/1t:

.lie it known that we -Unanivcn MoDAor;

and 'FRANK A. Ciminna', ,citizens of the linited States, residing, respectively, at Nlid-v in the counties ot.

dleport and Hartford,` Meigs'and Mason., States of Ohio and -\Vest `vlirginim have invented a new and useful lilinergeney-Vlank for Automobiles, ot which the iollowingisa specification.

lt is the object of .this invention to provide novel means whereby a. supply of gasolene may. be provided Aor'the carburetor of an'internal combustion engine, under circunistances arising when the main supply tank proves ineli'eetive for" this purpose,

such, for instanceas when the vehicle is ascending a steep hill.

,A furtherobjectfof thev invention is to provide nin/el means wherebyv a reserve supply of gasolenemaybe delivered upon-oc# casion.V l

'itis within the province ofthe disclosure,

to improve generally and to yenhance the utility of devices of thattype towhich the resent invention appertains.

-W'ith the above and other objects in view which will appear as the description pro` ceeds, theinvention ,residesin the combination andv arrangement ol parts andin the detailsof construction hereinafter ldescribed and claimed, it being imderstood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what' isf-claimed, without departing from the spirit oi? the invention.

ln the accompanying drawings, the nlllneral 1 denotes an internal combustion engine with which is assembled a earbureter 2.

A primary conduit 3 leads from the car- -bureter to a main supply tank 4 shown dia- `Speetatifm of Letters Patent.y

The numeral 7 denotes a T-shaped valve casing includinga depending neek- 38.v Unepart5cltheprnnary conduit 3 is connected by inea ns oi a threaded screw plug 9 with one e'nd oi the valve. vcas- `received in (menings lll in wings consti'f tuting a. part ol'la U-shaped body 1G sup-l plied with'j'an opstanding valve 17 having aprojection 18. The ear 11 is received between the wings 15 and the'projection 18 is received in the inner end'olf the passage 1() in the screw plug 9. The wings 15 are heavy enough so that the valve 1.7 'stands in open position7 normally, with respect to the inner end ol tl'1e'\.1 assago1(),and ,in order that an adequate opening of the valve 17 inay be possible, the `body portion ol' the valve casing 17 may be supplied with a depression 1) receiving the front lower corners ol' the wings 15.- v y A conduit 2() leads `l'ronx the lower end olI the neck 33 to the. lower coi'npartn'ient 2l. o'll an auxiliary tank 22 supported ar indicated at 23, of which the engine l constitutes a. part. 'lhe auxiliary vtank 22 has an internal substantially horizontal partition 24 separating the lower'compartment 21. lirom'an upper cornpartn'lcnt 25 in the auxiliary tank 22.

The partition 24 has a seat 26 with which cooperates a vertically moving, gravity closed valve 27 having a. nose 28 which depends into the seat 2G. Assembled with the valve 27 is an upstanding stem 29 which projects into a nipple 30 carried by the top of the auxiliary tank 22, the nipple 30 being closed by a removable cap 31. The top ol cach tank is supplied with an opstanding tube 32 carrying a seat 33. Extended across the tube 32 adjacent the lower end thereof is a guide-3ft in which reciproeates a stem 35, provided at its upper end with a valve 36 cooperating with the seat 33. Secured to the lower end of the stem is a 'float 37.

In practical operation, and under ordi* nary Working conditions, the valve 17 stands in an open position with respectito the pasin any desired manner, on the vehicle` Patent-ea Mar. ie, rais..A

Application led-April 18, 1917. SeralNo.162,944. A I

when the vehicle is traversing a steep hill, it-

is necessary to supply gasolene to the carbureter 2, independently of the main tank 4.

' Under ordinary working conditions, gasolene 'discharged into the valve casing 7 traverses the conduit 20 and enters the lower compartment 21 of the auxiliary tank 22.

lWhile the compartment 21 isbeing filled with gasolene, the valve -27 is raised by air pressuretin the compartment 21, and the air in the compartment 21 passes into the compartment 25, and out of the compartment 25 by Way of the tube 32. lVhena sufiicient quantity of gasolene has accumulated in the compartment 21, the gasolene, raising the valve 27 enters and fills the compartment 25.'

As the gasolene accumulates in the cona-l partment 25, airis permitted to flow outwardly through the seat 33- of the compartment 25, but when enough gasolene'has accumulated in the compartment 25, then the corresponding float 37 will rise, and the valve36 thereof, cooperating with the said seat 33 will prevent gasolene in 4the compartment 25 from being forced out of the said compartment,

It being presupposed that there is a-supply of gasolene in the lower compartment 21, the gasolene, when the vehicle is traversing a hill, will iow through the conduit 20 into ythe valve casing 7 and closethe valve 1'?, by pressure, so that this reserve supply of gasolen'e will not iind its Way into the main tank 4, as distinguished from the carbureter 2, b v way of the conduit 3. VA supply of gaso ene, therefore', will be given to the carbureter 2, under the circumstances above mentioned.

The operator may at any time remove the cap 31 and liftup the valve 27 by means of the stem 39. Under such conditions, the reserve supply of gasolene in the compartment 25 will flow into the compartment 21 through the seat 2G. The general structure of the device is suchl that a suiiicient supply of gasolene for the carbureter 2 will be afforded, when the vehicle is working on a hill and, further, the

operator of the car will have at hiscomfV vantage when the main tank 4 has been'per-l mitted to become empty.

Having thus described the invention, what 1. In a device ofthev class described, an

bureter; a valvevcasing interposed in the primary conduit; a connection uniting one end of the valve casing with the conduit; a swinging valve carried by the Vconnection and constituting means for controlling the passage of fluid through the connection,'the valve being counterbalanced to stand open, normally; an auxiliary tank; and a conduit bureter.; a check valve interposedv in the primary conduit; an auxiliary tank having a partition dividing the'auxilia'ry tank into upper and lower compartments; a Second conduit leading from the lower comparte ment to the auxiliary tank and communicating with theprimary conduit in advance of the check valve; a valve in the partition and controlling the passage of fluid from the upper compartment to the lower compartment,-

the said valve being under the control of an operator, and. being .upwardly movable, into an open position, under pressurecreated within the lower compartment, 4to permit a filling of the upper compartment. In testimony that we claim the fioregoin as our own, we have hereto affixed our signatures in the presence of two witnesses.
